Send 24-hour Hacker News trends to Telegram with OpenRouter AI translation

Stay ahead of the curve with this smart Hacker News monitor. Unlike simple RSS feeds, this workflow uses a custom "Gravity Score" algorithm to identify rising trends and filter out noise, pushing a clean, summarized digest to your Telegram.

✨ Key Features 🧠 Smart Algorithms:

Gravity Score: Calculates popularity based on points, comments, and time (velocity), ensuring you see trending stories, not just old ones.

Noise Filtering: Automatically discards "infancy" posts (new posts with zero engagement) to keep your feed high-quality.

🤖 Optional AI Translation: Includes an AI Agent (via OpenRouter/LLM) to translate titles and summaries into your local language (e.g., Chinese, Spanish, French).

> Don't need translation? Simply delete the Translate node and connect the Filter node directly to the Combine message templates node.

📱 Beautiful Telegram Format: Delivers a clean HTML-formatted digest with clickable links, stats (Points/Comments), and story previews.

⚙️ How It Works Schedule: Runs every 4 hours (configurable) to fetch data from the past 24 hours via the Algolia API.

Analyze: Calculates the velocity score for each post and filters out low-quality entries.

Translate (Optional): Uses an LLM to translate the content. You can customize the target language in the AI Agent's system prompt.

Format & Send: Combines the data into a structured message and pushes it to your Telegram Chat/Channel.

📝 Setup Instructions Telegram Credentials:

Add the Bot Token to the Telegram node credentials.

AI Configuration (Optional):

Configure your LLM credentials (e.g., OpenRouter, OpenAI).

In the "Translate" (AI Agent) node, edit the System Prompt to change the target language (Default is set to translate to Chinese).
